Abstract: 1, 104, 028. Fuel injection systems; reciprocating pumps and motors. SULZER BROS. Ltd. Sept. 13, 1966 [Sept. 14, 1965], No. 40839/66. Headings F1A and F1B. In a fuel injection system a fluid-pressure actuated pump 15, supplied with actuating fluid via a pressure controller 38, delivers fuel to an accumulator V connected to a fuel injector 1. Oil is delivered alternately to the chambers 26 and 27 on opposite sides of the motor piston 25 from an engine driven or separately driven pump 40, at a pressure set by the controller 38, under the control of a rotary valve 35. The pump pistons 19 deliver fuel to the accumulator V at a pressure determined by the controller 38. The operation of the injector 1 is controlled by a control element 16 which connects the injector chamber 10 alternately to the pump delivery line 14 or a line 17 communicating with the fuel reservoir 18 to cause operation of the injector needle 3. A valve element is adjustable axially within the element 16 by means of a lever Q to vary the opening period of the injector 1 and an adjustor T is provided for adjusting the injection timing in relation to the engine crank-shaft driving the control through gears A. The pump 15 may supply a plurality of accumulators and injectors. The injector 1 may be opened by mechanical or electrical means. In a further embodiment, Fig. 2 (not shown), the opposite sides of the motor piston (53) are connected to pressure and exhaust alternately by a slide valve (50) which is moved by the oil pressure and controlled by movement of the motor piston. The slide (100) in the slide valve (50) reverses the connections to the piston (53) when the piston reaches the ends of its strokes. The fuel pump may comprise an hydraulic gear-wheel pump and motor combination.

[Also in Division G4] An input-output arrangement for a digital computer comprises a display screen for displaying a visual pattern of information and photo-electric means for detecting a light occultation effected in the displayed pattern by the computer operator. As described, a cathoode-ray tube 1 is employed as a screen 21 for displaying the pattern of a draught board and pieces for use in a game of draughts played between the computer 16 and the computer operator, but the arrangement may also be used for other purposes, e.g. controlling switches. The draught board raster 121 may be a translucent mask or may be formed by electronic scanning control. The raster 121 is continuously scanned in response to 4-bit control signals supplied from the computer 16 over leads 17, 27, data being supplied also to a lead 20 to indicate, by supplying appropriately modulated signals, whether the square currently scanned is empty, or is occupied by a piece, or " king," pieces being indicated by a square or a circled " kings " by two concentric squares or circles. Photo-cells 131-134 co-operate with the C.R.T. screen 21 and to effect a move in the game, the computer operator places an opaque object against the square from or to which a piece is to be moved, the resulting occultation being detected by the photo-cells 131-134 to cause a circuit 15 to signal the move to the computer 16, which counts and processes successive occultations to cause the desired move to be effected. The computer 16 checks that the move is allowable and then produces its own move.

Patent GB-1114549-A (GB)
Title: Glass covered semiconductor device and coating glass therefor
IPC: C03C3/074
Filed: 1966-09-14
Abstract: A glass consists essentially, in weight per cent, of ZnO 60, B2O3 23-25, SiO2 9.4-10.5, CeO2 3, Bi2O3 0-0.1, PbO 2-3, Sb2O3\t 0.5. This glass is used to coat an electrical device such as diode, including a silicon crystal semi-conductor element in the form of a wafer with electrical conductors connected to either side of the wafer, by applying the glass in finely divided form to the surface of a semi-conductor device comprising an N-type region and a P-type region with each region fused to an aluminium contact, each contact being bonded to a heat sink electrode member selected from (a) molybdenum; (b) tungsten; (c) an iron base alloy with 28-30% Ni, 15-18% Co and a fractional amount of Mn, to form a coating extending partially over and in sealing relation with each of the heat sink members, the surface with the coating thereon being heated to melt the glass particles together into a unitary mass sealed to the body. The coating may be applied in the form of a slurry, prepared by mixing powdered glass with a conventional organic binder, such as nitrocellulose, and a vehicle, such as deionized water, the slurry being sprayed or painted on to the substrate.  The assembly is heated to drive off the binder and the vehicle, and the coating vitrified by heating at 775 DEG  to 825 DEG  C. for 2 to 5 minutes, vitrification taking place in an inert atmosphere, or in a vacuum, to prevent oxidation of the molybdenum parts of the diode. Prior to applying the glass coating the semi-conducting body and sealing surfaces of the heat sink members may be cleaned by etching to remove undesirable contaminants.  Several layers of coating may be applied to produce the desired thickness, a thickness of at least 10,000 Angstroms being desirable.  The coefficient of thermal expansion of the glass used may be controlled by heat treatment to be within the range 37.5 x 10-7/ DEG  C. to 44.9 x 10-7/ DEG  C., the powdered glass being heated in graphite moulds for various times and temperatures to provoke nucleation of the sintered glass. The coefficient of expansion of the coating glass can be selected to match that of the electrically conducting parts of the diode.
